The present invention provides a method for service error connection and error prevention in automatic switched optical network (ASON), which is used to resolve the technical problems that the traditional method for error connection and error prevention cannot realize the rapid automatic configuration, and the efficiency is low and so on. The present invention overcomes the defect that the manual setting is error prone by automatically completing the error connection and error prevention configuration of the first and end nodes by the control plane; and it is rapid and simple to complete the interaction of the error prevention information of the first and end nodes by exchanging the protocols. The present invention enables the automatic complement of the error connection and error prevention configuration for the first and end nodes through the control plane, and enables the automatic citation of the error connection information of the source connection on the new connection of the service in various error prevention strategy conditions when the error connection alarm occurs, thus enhancing the usability of the system and the robustness of the service to a great extent. |
